WASHING-MACHINE.

SPECIFICATION forming: part of Letters Patent N o. 659,603 dated October 9, 1900.

Application filed July 11,1900. Serial No. 23,268, (No model.)

To mil whom, it may concern:

Be it known that I, J OHN HENRY Bunsen, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in WVashing-Machines; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable o1 hers skilled in the art to which it appertains to make and use the same, reference being had to the aceom panying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in wishing-machines; and it has for its object to pivot the body and cause a rocking motion of the body upon it s pivots to operate the stirrer.

My invention consists in a suitable framework, a tub pivoted therein, so as to have a rocking motion, suitable guides secured to the top of the tub, and a yoke raised a suitable distance above the cover and having a risingandfalling movement and over which the guides move as the tub is reciprocated, whereby the yoke is always kept the same distance from the top of the cover while in motion, combined with a stirrer-shaft which extends through the coverand has secured to its lower end a stirrer and to its upper end a pulley, and a cord or cords secured to opposite ends of the yoke and wrapped around the pulley, so that by swinging the tub the guides are made to move back and forth over the yoke, thus rotating the stirrer first in one direction and then in the other. Heretofore the stirrershaft has been made to reciprocate 'by means of a cord or cords wrapped around a pulley secured to the shaft; but never before have guides been provided for the yoke, so as to brace and support the parts and have the parts move evenly and true at all times and keep the yoke the same distance above the cover.

In the drawings, Figure 1 represents a plan view of a washing-machine which embodies my invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a detail View of one of the yoke-guides.

A represents the frame, which is braced near its lower end by the cross-piece B. The uprights of the frame are curved as shown in Fig. 2, so as to conform to the shape of the tub, and are provided near their upper ends with pivot-plates C, in which the pivots D upon the tub have their bearings. The cover E of the tub' has mounted thereon a suitable casting F, and passing down through this casting is the stirrer-shaft G, which has the stirrer H secured to its lower end and the pulley I secured to its upper one. This casting has the two curved arms J rising from its top, and these form a bearing K for the upper end of the shaft G, in the usual manner. the cover are mounted castings L, which form supports at their upper ends for the yoke M. This yoke, as shown in Fig. l, is oblong at its center and has extending therefrom the arms or extensions N, which pass through the guides O, and which extensions are provided with friction-rollers P at their ends. These extensions extend in a line with the uprights of the frame, and the ends of the extensions catch in vertical slots in the uprights, so that while the tub reciprocates back and forth the yoke is held stationary, with the exception of a slight rising-and-falling movement, as the tub is rocked back and forth upon its pivots. While the guides are carried back and forth with the tub, being secured to its cover, the yoke is held in the guides, and it will always be a uniform distance from its top as the guides move back and forth over the'extensions. Secured to opposite ends of the yoke, as shown in Fig. 1,is a cord or cords Q, which are wrapped around the pulley I, so that as the tub swings upon its pivots the stirrershaft is made to revolve first in one direction and then in the other, in the well-known manner. Each of the guides is provided wit-h a slot through which the extension N of the yoke passes, and hence the yoke is always kept the same distance from the cover of the tub while in motion, the ends of the yoke rising and falling in the slots in the frame, so as to accommodate the movement of the guides.

As shown in Fig. 2, one of the extensions of the yoke is curved downwardly, so as to be nearer to the cover of the tub than the other, and the guide for this turned-downwardly extension is of a less height than the other. The extension upon the yoke is curved downwardly, as shown, so as to enable a wringing-machine to be secured thereto and which Upon opposite sides of the centerof' wringer need not be removed while the washing is going on. The extensions N of the yoke M extend at right angles to the hinges of the cover, and the ends of the extension being free to rise and fall in the slots in the upper ends of the uprights the cover can be freely raised and closed at any time without displacing the wriuger or any other part of the machine. For the purpose of operating the cover it is provided with a suitable handle for that purpose. When the cover is raised, the end of one extension rises out of the slot in the upright of one side of the frame, while the end of the other extension sinks in the slot in the upright upon that side. While the tub is rocking upon its pivots, this yoke h as a slight turning movement upon its pivots, so as to accommodate itself to the curve through which the guides swing or move.

By means of the construction here shown it is only necessary to rock the tub upon its pivots to cause the stirrer-shaft to rapidly revolve first in one direction and then in the other, and the yoke having a slight risingand-falling movement the cords are always kept the same distance above the top of the cover of the tub, and hence a uniform movement of the stirrer is kept up.

Having thus described my invention, I claim-- 1. In a washing-machine, a suitable framework, a tub pivoted therein, and suitable guides secured to the cover of the tub, combined with a yoke over which the guides move, cords secured to the yoke,-and a stirrer-shaft provided with a pulley at its upper end and a stirrer at its lower one, substantially as shown.

2. In a washing'maehine, a suitable f amework, a tub pivoted therein. the cover of the tub, and the stirrer-shaft pivoted in the cover and provided with a pulley at its upper end and a stirrer at its lower one, combined with guides secured to the cover, a rising-and-falling yoke which extends through the guides and has its ends held in slots in the upper end of the framework, and a suitable cord or cords secured to opposite ends of the yoke and passing around the pulley upon the stirrer-shaft, substantially as set forth.

3. In a washing-machine, a suitable framework, a tub pivoted therein and provided with a cover, and a stirrer-shaft projecting through the cover of the tub, combined with guides secured to the cover, and a yoke having a rising-and-falling movement in relation to the frame, and which yoke is held in place by means of extensions upon its sides which pass through guides and loosely engage the upper end of the framework, and means connected to the yoke for causing the stirrershaft to revolve as the tub is rocked upon its pivots, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN HENRY BUEGGE.
